Agreed.  I noticed this issue, too, but forgot about it later.
Would you mind filing a PR with me in Cc so that I won't forget
about it again?  Can't promise making the order arbitrary, but
documenting this subtlety is a must.

Just use:

  ifconfig_vlan14="inet W.X.Y.Z netmask 255.255.255.0 vlan 14 vlandev fxp0"

This is what ifconfig(8) manpage tells in the syntax section:
the address should precede other parameters.
